2022) Oil spill detection based on texture analysis: how does feature importance matter in classification? ABSTRACT Oil spill mapping and detection represent a relevant issue from an environmental point of view, given the effects on marine ecosystems. This study presents a new feature space assessment protocol for oil spill mapping using the Google...

The current study aimed to obtain dose conversion coefficients for marine animals due to an oil spill accident using two variables: crude oil activity concentration and organism depth. Thorium series presented a dose contribution twice that uranium series for similar conditions. Bi-214 and Tl-208 stood out for delivering a higher dose rate for uran...

Abstract Three SAR-derived observations of dark surface patches along the Northeastern Brazilian coastline by the end of 2019 were misreported in the Brazilian media as oil spill-related. Unfortunately, these observations were misled by false positives or look-alikes. Therefore, this paper aims to technically evaluate these look-alike classes by an...

To effectively combat the COVID-19 pandemic, countries with limited resources could only allocate intensive and non-intensive care units to a low number of regions. In this work, we evaluated the actual displacement of infected patients in search of care, aiming to understand how the networks of planned and actual hospitalizations take place. To as...
Preprint
To effectively combat the COVID-19 pandemic, the state government of Bahia, Brazil, has distributed intensive and non-intensive care units along the nine regions that divide the state of Bahia, such that COVID-19 patients could be easily hospitalized in health care units located at the same regions where they live. However, the observed hospitaliza...

A set of open-source routines capable of identifying possible oil-like spills based on two random forest classifiers were developed and tested with a Sentinel-1 SAR image dataset. The first random forest model is an ocean SAR image classifier where the labeling inputs were oil spills, biological films, rain cells, low wind regions, clean sea surfac...

A combination of bibliometric and science mapping methods was carried out to explore characteristics of scientific production on the application of orbital remote sensing in fire ecology. The performance analyzes made it possible to identify the main actors responsible for the knowledge (authors, institutions and countries) and the journals selecte...
Article
The new Covid-19 pandemic has left traces of suffering and devastation to individuals of almost all countries worldwide and severe impact on the global economy. Understanding the clinical characteristics, interactions with the environment, and the variables that favor or hinder its dissemination help the public authorities in the fight and preventi...

As mudanças na estrutura e configuração das paisagens, oriundas de processos naturais ou antrópicos têm motivado um aumento nos estudos em Ecologia de Paisagens nos últimos anos. Os modelos neutros de paisagens surgem como uma possibilidade de entender tais mudanças, uma vez que a configuração e arranjo dos ambientes na paisagem são determinados po...

Oil spill detection and mapping (OSPM) is an extremely relevant issue from a scientific point of view due to the environmental impact on coastal and marine ecosystems. In this study, we present a new approach to assess scientific literature for the past 50 years. In this sense, our study aims to perform a bibliometric and network analysis using a l...

Brazil has a monitoring system to track annual forest conversion in the Amazon and most recently to monitor the Cerrado biome. However, there is still a gap of annual land use and land cover (LULC) information in all Brazilian biomes in the country. Existing countrywide efforts to map land use and land cover lack regularly updates and high spatial...

In this study, methods, originally developed to assess life course trajectories, are explored in order to evaluate land change through the analysis of sequences of land use/cover. Annual land cover maps which describe land use/land cover change for the 1985–2017 period for a large region in Northeast Brazil were analyzed. The most frequent sequence...

Some nymphalid butterflies obtain their nutrients from fermented fruits or plant saps. They compose a guild known as "fruit-feeding butterflies," a recognized biological indicator. We gathered a huge data set of fruit-feeding butterfly communities in a recent paper for Ecology. The data set contains 7,062 records of 279 species from 122 locations,...

Durante os últimos anos, foram criados diferentes pacotes de R dirigidos à análise espacial. Ainda assim, existem poucos livros focados na análise espacial com R2. Este livro destina-se a usuários com conhecimento básico de Sistemas de Informação Geográfica (SIG) que desejam iniciar a gestão e análise de dados espaciais com R. Portanto, não requer...

Butterflies are one of the best-known insect groups, and they have been the subject of numerous studies in ecology and evolution, especially in the tropics. Much attention has been given to the fruit-feeding butterfly guild in biodiversity conservation studies, due to the relative ease with which taxa may be identified and specimens sampled using b...

Although the Earth Observing One (EO-1) satellite was launched as an experimental platform through NASA's New Millenium Program, it has completed more than seventeen years of activity, imaging the Earth through its two unique instruments, the Advanced Land Imager (ALI) and Hyperion. Hyperion in particular was the only hyperspectral instrument to ha...

Large areas in tropical countries were converted into Eucalyptus plantations for pulp production. Although these plantations are structurally more similar to native ecosystems than traditional short-lived crops, they can be less suitable for more sensitive species. Thus, it is important to know how they can harbor native biodiversity and contribute...

Este artigo propõe um método para mapear e qualificar a inserção social dos Programas de Pós-Graduação (PPG) na área de Ciências Ambientais da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES). A construção do modelo consistiu na integração espacial de três componentes: o índice de vulnerabilidade socioeconômica (infraestrutura, c...

Em função da constatação da crise ambiental vivenciada nas escalas globais, regionais e locais, decorrentes da exploração intensa do patrimônio ambiental, torna-se relevante detectar as mudanças de uso da terra e da cobertura vegetal, a fim de identificar os níveis de degradação ambiental ao longo do tempo. Nesse contexto, surge o projeto Mapbiomas...

Eucalyptus plantations are increasing in Brazil, frequently replacing pastures, but there is still scarce information about its capacity to maintain the fauna of neighbor forest remnants. In this study, we compared descriptors of the communities of leaf litter organisms (lizards, anurans, myriapods, arachnids, orthopterans, coleopterans, and ants)...

The “Synthesis in Atlantic Forest Ecology and Sustainability Group” initiated its activities with the mission to develop studies aiming to synthesize knowledge on ecology and sustainability in the Brazilian Atlantic Forest ecosystem. The group aims to test hypotheses and answer key questions on ecology and sustainability using an extensive empirical multi-taxon database obtained within the Atlantic Forest. The group relies on the participation and knowledge of a large number of colleagues, the combined expertise of whom contributes to the studies realized by group members. The group was founded and is coordinated by scientists from different universities, namely Jayme Prevedello (UERJ), e Thomas Püttker (UNIFESP), Renato Crouzeilles (IIS/CSRio), Mauricio Almeida-Gomes (UFMS), Jean Paul Metzger (USP), Renata Pardini (USP), Cristina Banks-Leite (Imperial College-London), Marcus Vinicius Vieira (UFRJ), Marcelo Tabarelli (UFPE), Pedro Brancalion (ESALQ-USP), Bernardo Strassburg (IIS/CSRio/PUC-RJ), and Carlos Fonseca (UFRN).
